. MACHINE FOR BORING, PLANING, AND SLOTTING- vIVICKE'IAIS.

Specification of Letters Patent 1\T o. 12,117, dated January 2, 1855.

To all Awhom t may concern.'

Be it known that I, NORMAN AmisL woR'rr-r, of. Rochester, in the county cf Monroe, in the State of New York, have invented 'a 1 fw and Improved Machine for Turning, Boring, and Cutting Key-Seats in Carl/V heels or any other Work; and I vdo hereby declare that the following is a full and exact description thereof, reference being had to the annexed drawings and to the letters of reference marked thereon.

The nature of my invention consists in so arranging the several operative parts of a machine for turning, boring, andl cutting key seats, as that the three several opera.- tions may be completed from the same cen- 1ers', without unchucking the piece of machinery to be so wrought'upon, by which means more accurate workvcan be done, with less labor, than when the piece is removed or rechucked, in two or more machines.

construct ymy machine with ythree columns resting on a triangular base, y'with a triangular arch on the top of the 'columns and which is supported by the columns. In the center of the arch supported by the columns there is an upright mandrel which passes through a hub. I attach, at the lower end of the mandrel a tool'stock with rimmers and Glitters for the purpose of boring a car wheel. I also attach totwo of the columns a cross head which works up and down on the columns; to the cro-ss head` I attach a sliding head .which carries a cutter horizontally for the purpose of turning the hub of the wheel at the same time that it is bored and with the same motion.

In my'machine the wheel to be turned and bored revolves instead of the drill, and the drill is fed down through they wheel by means of gearing abo-ve the arch, the

,sliding head is also fedb-y a screw so as to turn the hub ofthe wheel at the same time that it is drilled, so that the wheel is` bored and drilled with the samemotion and consequent-ly more perfect than it .otherwise would be, and thereby saving the time of turningk the hub of the wheel.` I also make use of the upright mandrel for the purpose of cutting a keyseat in the hub ofthe wheel, without changing the position of the wheel, so that a wheel may be putonto my machine and .turned off, bored and a keyseat cut without changing kthe lposition of the wheel.

i In `order that my invention may be more fully understood I will refer to the annexed drawings.

Figure 1 shows a front elevation or work side of my machine. Fig. 2 shows aside elevation. Fig. 3 is .a view of my machine as seen when looking directly down'upon it. Fig. 4L shows a section through A B, Fig. 2.

YWhen the mandrel "Q is brou-ght.ilown the tool'stock, passes down'into thesp'indle H, for the purpose of steadyingzthe cuttersy and rimmers. The mandrel Q does'inotrevolve' but wo-rks 11p-fand down inthe hubJF.l There is to be a 'feather rmly fixed finto the hub F, and a groove cut in the mandrel which works on thefeather, and which prevents the mandrel from revolving.

In turning and boring a car wheel, I place the wheel on the revolving table or face plate and fasten it in a proper position by .means of the dogs shown B B and C, Fig.

3, as has been described. I then pass the tool stock down through the hub of the wheel so that the lower end of the tool stock enters the upper end of the spindle. I then set the revolving table in motion by means of the shaft Y, Fig. l, and when the shaft Y is put in motion, the shaft T, Fig. l, revolves and the worm'operating in the worm gear causes the mandrel Q to move down and the cutter V being attached to the tool stock R R, is moved down and bores the wheel, and by the hand wheel O the turning tool P is moved down in a proper position for turning off the hub of the wheel. By means of the hand wheel N I give a horizontal motion to the turning tool P, so that it will be seen that the wheel is bored and turned at the same time, and with the ,same revolving motion, and thereby done more perfectly and in less time than it could be if the boring and turning were done separately.

In order to cut a keyseat as a slot in a car wheel, I stop the motion of the revolving table or face plate, and throw the Worm con nected with the shaft T, out of gear, and also take out the tool stock R R which is placed in the mandrel Q and put into its place a tool stock with .a cutter properly made for cutting a keyseat. I then give a motion to the nut S by means of the pinion b it being driven by the belt c or Z and by means of the clutch between the two pulleys, on which the belts work. I reverse the motion alternately, causing the mandrel to work up and down, andby means of the tool stock which is placed into the mandrel Q in the place of the tool stock R R having a proper cutter attached which passes down and up, through the hub of the wheel, the keyseat is cut.

Having t-hus fully described the nature of my invention, what I vclaimtherein as new and desire to secure by Letters Patent is- The so arranging of the several operative partis of a machine for turning, boring, and

cutting key seats, in car Wheels, cranks and other machinery, as that the three several operations may be completed from the same centers, without unchucking said piece of machinery, by which means more perfect work can be done, than when the piece so removed or rechucked, for two or more successive operationsthe wheel being achieved in the manner set forth. v
